San Joaquín Wastewater Treatment Plant, Colima, Mexico

The San Joaquín wastewater treatment plant is located in the municipality of Cuauhtémoc, Colima, Mexico. It serves a small population of 913 residents, reflecting its role in a rural or peri-urban community. The plant is situated inland, away from coastal areas, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is appropriate for its scale and typical for small communities in Mexico. With a designed capacity of 129.60 cubic meters per day and an actual discharge volume of 86.40 cubic meters per day, the facility operates below its capacity. This suggests room for future growth or seasonal variations in flow. The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the Armería River basin. The plant helps protect downstream ecosystems and water quality in the region, supporting agricultural and ecological uses of local waterways.

The plant's discharge enters the local drainage network within the Armería River basin, which flows westward to the Pacific Ocean. This watershed supports diverse aquatic life and agricultural activities. Proper treatment is essential to prevent nutrient loading and contamination that could affect downstream communities and coastal ecosystems.
